摘      要：Various colors have been used as visual cues to trap insect *** example,yellow traps for monitoring and control of the whiteflies have been in use for a very long ***,the chromatic cue of using color traps has never been quantitative *** this study,RGB values and wavelengths were changed each other based on Dan Bruton’s wavelength to RGB function..Eight colored papers printed by color printer based on RGB values[(0,213,255),(0,255,146),(54,255,0), (129,255,0),(195,255,0),(255,255,0),(255,190,0) and(255,119,0)]were chosen to test the color preference of spirlling whitefly,Aleurodicus dispersus in a octagon *** approximate wavelengths were 480,500,520,540,560,580,560 and 600 nm *** color papers with the spectrum between 530～570 nm showed the higher attraction than other color papers,and 550 nm (chartreuse,RGB 163,255,0) showed the highest attracted *** additional,field preference test was done to confirm the effect of the chartreuse *** was concluded that chartreuse stimuli(spectra:550 nm) should be a crucial cue to attract the spirlling whitefly,***.
